Abstract
The invention discloses a compensation cable special for a low temperature resistant thermocouple. The cable comprises two or more cable cores, compensation wire cores, a ceramic fluororubber outer sleeve, a copper-clad steel armored layer, a flame-retardant mica tape and a tinned wire woven shielding layer, wherein each cable core is formed by pressing and wrapping a SiO2 ceramic insulated layer on a nickel-chromium-nickel-silicone alloy conductor; the upper and lower gaps between every two adjacent cable cores are respectively provided with a compensation wire core; the copper-clad steel armored layer, the flame-retardant mica tape and the ceramic fluororubber outer sleeve are pressed and wrapped on the tinned wire woven shielding layer sequentially from inside to outside. The temperature loss of the cable is compensated through the compensation wire cores, so that a product can normally work in an environment with the temperature between 80 DEG C below zero to 500 DEG C in a long term, and good flame-retardant performance and radiation resistant performance are realized, the cracking phenomenon caused by temperature shock is reduced, the signal smooth is ensured, and the service life is prolonged.
Description
Technical field
The present invention relates to cable, relate in particular to the special compensating cable of a kind of low temperature resistant thermocouple.
Background technology
Up to now, the special compensating cable of a kind of low temperature resistant thermocouple is widely used in the fields such as metallurgy, casting, oil refining, chemical industry, machinery, especially in the adverse circumstances of low temperature, the conventional cable of the signal transmssion line of electrical instrumentation and automation control system is usually because temperature is too low, cause cable easily damaged under low-temperature impact, signal transmission is influenced, causes instrument system at low temperature and emergency circumstances cisco unity malfunction, has caused huge loss.
Summary of the invention
According to above-mentioned situation, the object of the invention is to provide the special compensating cable of a kind of low temperature resistant thermocouple.
The solution of the present invention is as follows: the special compensating cable of a kind of low temperature resistant thermocouple, comprise two or many cable cores, compensation core, ceramic fluorubber oversheath, copper covered steel armour, fire-retardant mica tape and tin plated wire woven shields, described cable core is to be extruded on nickel chromium triangle-nickel silicon alloy conductor and to be formed by SiO 2-ceramic insulating barrier; Described compensation core is to extrude heater by heat conduction sheath to form; Described tin plated wire woven shield extrudes two or many cable core levels; Between every two adjacent cable cores, upper and lower gap location arranges a compensation core; Described copper covered steel armour, fire-retardant mica tape and ceramic fluorubber oversheath are from inside to outside extruded on tin plated wire woven shield successively.
Beneficial effect of the present invention: the present invention is by the temperature loss of compensation core compensating cable, product can normally be moved for a long time in the environment of-80 DEG C to 500 DEG C, and there is good anti-flammability, radiation resistance, reduce the cracking phenomena that temperature shock causes, inhibit signal is unimpeded, has greatly extended the life-span.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Wherein: 1, ceramic fluorubber oversheath; 2, copper covered steel armour; 3, fire-retardant mica tape; 4, tin plated wire woven shield; 5, nickel chromium triangle-nickel silicon alloy conductor; 6, SiO 2-ceramic insulating barrier; 7, heater; 8, heat conduction sheath.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, the special compensating cable of a kind of low temperature resistant thermocouple, comprise two or many cable cores, compensation core, ceramic fluorubber oversheath 1, copper covered steel armour 2, fire-retardant mica tape 3 and tin plated wire woven shields 4, described cable core is to be extruded on nickel chromium triangle-nickel silicon alloy conductor 5 and to be formed by SiO 2-ceramic insulating barrier 6; Described compensation core is to extrude heater 7 by heat conduction sheath 8 to form; Described tin plated wire woven shield 4 extrudes two or many cable core levels; Between every two adjacent cable cores, upper and lower gap location arranges a compensation core; Described copper covered steel armour 2, fire-retardant mica tape 3 and ceramic fluorubber oversheath 1 are from inside to outside extruded on tin plated wire woven shield 4 successively.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and amendment; when its function producing does not exceed spiritual that specification contains yet, all should be within protection scope of the present invention.
